# show-methods: Methods for Function 'show' in Package 'partsm' In partsm: Periodic Autoregressive Time Series Models

## Description

This method shows the information provided by functions implemented in package 'partsm'.

## Methods

object = "fit.partsm".

Shows the estimates of the autoregressive or periodic autoregressive coefficients.

object = "Ftest.partsm".

Shows the F-test statistic, the null and the alternative hypotheses entailed in the procedure, as well as the freedom degrees, the p-value and a symbol indicating the significance of the F-statistic according to usual codes, i.e. Signif. codes: 0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1.

object = "fit.piartsm".

Shows the estimated periodic autoregressive coefficients in the restricted non-linear PIAR.

object = "LRur.partsm".

Shows the LR statistics and a one-side test constructed as sign(g(\hat{α}) - 1) * LR^{1/2}, where g(\hat{α}) is the product of the periodic differencing filter parameters estimated under the alternative.

object = "pred.piartsm".

Shows out-of-sample forecasts and the corresponding standard errors, as well as the 95 per cent confidence intervals.
